   　SEIJI excels at depicting intense battle scenes and is also highly skilled at expressing character appeal. In 2020, he collaborated with PONJEA to create a manga adaptation for the popular mobile game IP “Hortensia SAGA” during the broadcast period of its television anime. The manga was published in KADOKAWA’s print magazine “Monthly Comic Alive” and was also simultaneously serialized digitally on platforms such as “Kadocomi” and “Niconico Seiga.”
His recent representative manga work is “Tensei Shitara Joban de Shinu Chūboss Datta: Kenzokuka Skill de Ikinobiru,” adapted from the original novel by Inashita Taketō. The series is currently serialized on SQUARE ENIX’s “Gangan Online” and “Manga UP!” platforms. Built around the core appeal of reincarnation into a game world, monster familiarization, and overturning one’s destined death, the Japanese manga edition has currently been released up to Volume 11, with cumulative series sales surpassing one million copies.
